"The Oracle VM VirtualBox application installed on the remote host is a
version prior to 5.0.22. It is, therefore, affected by multiple
vulnerabilities in the bundled OpenSSL component :

  - A heap buffer overflow condition exists in the
    EVP_EncodeUpdate() function within file
    crypto/evp/encode.c that is triggered when handling
    a large amount of input data. An unauthenticated, remote
    attacker can exploit this to cause a denial of service
    condition. (CVE-2016-2105)

  - A heap buffer overflow condition exists in the
    EVP_EncryptUpdate() function within file
    crypto/evp/evp_enc.c that is triggered when handling a
    large amount of input data after a previous call occurs
    to the same function with a partial block. An
    unauthenticated, remote attacker can exploit this to
    cause a denial of service condition. (CVE-2016-2106)

  - Flaws exist in the aesni_cbc_hmac_sha1_cipher()
    function in file crypto/evp/e_aes_cbc_hmac_sha1.c and
    the aesni_cbc_hmac_sha256_cipher() function in file
    crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered
    when the connection uses an AES-CBC cipher and AES-NI
    is supported by the server. A man-in-the-middle attacker
    can exploit these to conduct a padding oracle attack,
    resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - Multiple unspecified flaws exist in the d2i BIO
    functions when reading ASN.1 data from a BIO due to
    invalid encoding causing a large allocation of memory.
    An unauthenticated, remote attacker can exploit these to
    cause a denial of service condition through resource
    exhaustion. (CVE-2016-2109)

  - An out-of-bounds read error exists in the
    X509_NAME_oneline() function within file
    crypto/x509/x509_obj.c when handling very long ASN1
    strings. An unauthenticated, remote attacker can exploit
    this to disclose the contents of stack memory.
    (CVE-2016-2176)");
